HAY-PRESS.

BECEFLECATION forming part of Letters Patent No. 334,8l3, dated January26, 1586.

Application filed June 16, 1885.

To all whom, it may concern:

Be itk nown that l, HENRY F. BLANK, a citizen of the United States,residing at Quincy, in the county of Adams and State of Illinois, haveinvented certain new and useful Improvements in Hay-Presses, and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to theletters and iigures of reference marked thereon, which form a part of this specification.

The object of my invention is to provide a hay-press having an improvedconstruction for the sweep and its connection with the follower, thebale-chamber, and the devices for affording frictional resistance to thehay forced through the bale chamber by the plunger; also devices forseparating the bales when discharging from the balechamber.

The nature of my invention will be described below, and pointed out inthe claims.

In the drawings, Figure 1 is aside elevation, partly in brok en section.Fi g2 is aplan View, partly in broken section. Fig. 3 is a rear view ofthe press. Fig. 4t is a detail sectional view of the fioor of the press,showing theoperation of the bale-separating hook.

Like letters refer to like parts.

4The press is mounted on wheels, so that it-can be moved from place toplace. The main frame consists of two lower beams, A A, resting on thetrucks,and the two upper beams,B B,separated from the lower bythe sideposts, C (l, of the bale-chamber, the said beams being strengthened atintervals by cross-pieces and bolts.

D represents the sweep, which is forked, the upper and lower sides beingheld apart by one or more cross-strips, af. The rear ends of the sweepare slotted at b, and there are transverse pins b' through the slots,bearing against rigid pins or bearings c, fastened, respectively, to thetop and bottom cross-pieces,c', ofthe frame, and it will thus be seenhow the sweep can swing to and fro. (See Figs. 1 and 2.) Between thesides of the sweep extends a rigid bolt, e, having aloose sleeve, e',about itslower half. On the top of this sleeve, and about the bolt, isone eye of the link E, the center of the link being solid, and the othereye playing Serial No. 168,884. (No model.)

about a bolt, d, in the double knuckle-lever F. This lever is centrallypivotcd about a vertical metallic shaft, F', stepped in metallicplatesf,

attached to the cross-pieces c', the hubs f' of 55 lever F bearingagainst said plates. The rear of said lever is pivoted by bolt d' tothepitman G, which is in turn pivoted to the plungerH by means of boltd2 and bracket The plunger is of ordinary form, except it has adownwardly-inclined groove, g, which in the forward throw engages with acorrespondinglyshaped cleat, g', on the roof of the frame, andpreventsthe plunger from coming too far for- Ward.

I is the bale-chamber, which should be long enough to include l apressing-chamber and a bale-compartment. The roof, floor, and sides ofthe pressing-chamber are solid; but the baledischarge compartment hashorizontal slots h h, so that the pressed bale may be readily tied withwire, Ste., before discharging. rEhe rear end of the discharge or wiringchamberis what may be termed a movable friction-head, J. Its inner faceis slotted at h h to match slots hh, and from its rear side extendsb'ack a geared rack, J', which gears with a pinion, K, on shaft K',which is journaled through the rear frame-posts, C' C. On one end ofshaft K' is a rigid pulley, L, surrounded by a frictionband, L', whichmay be loosened or tightened about the pulley by means ofatension-screw, Z. 'The said band is provided with stops or ratchets mm, dividing the former into segments, and` these engage with a clutch,M, pivoted to one of the lower beams at m'.

From the above (see Figs. 1 and 8) it will be evident that the head willyield sufficiently to the hay forced through the chamber I by theplunger, and that while the pulley L cannot turn to any great extentoutward before the clutch causes the band to exert a frictionstop, atthe same time the pulley is left free to turn inward by the clutch whenthe head Jis returning to place. By releasing the clutch the bale may bereadily discharged, as the pulley and its band will no longer operate.

To separate the discharging bales the following devices are used, (seeFigs. 1 2, and 4:) Below the beams A A is pivoted a lever, N, the handleof which plays in aguide, a. To

the upper side of the lever is loosely attached IOO a block, O, (seeFigs. 2 and 4,) the upper part of which isT-shaped, and its play isguided by a U -shaped groove, n', ineaeh of the crossstrips P P betweenthe lower beams, A A. rBhe forward end of the T-head -is Wedgeshaped,(see 0,) and when this strikes the pivoted hook R the latter is liftedwell up through a slot, r, in the oor of the bale-chamber, forming aneffectual stop to what is back of it.

Having fully described myinvention, what I claim, and desire to secureby Letters Patent, is-

l. The combination of the forked sweep,piv `oted to the top and bottomof the frame outside ofthe double knuckle-lever and its shaft, withalink connecting the sweep to the forward end of the leveigthe saiddoubleknucklelever, a pitrnan hinged to the rear side of it and theforward end of the plunger, and the said plunger, as set forth.

2. The sweep pivoted to the frame at both ends of the fork outside ofthe doubleknuokle lever and its shaft, and having a bolt provided with acollar, combined with the double-looped link, the double knuckle-leverand its central 25 vertical shaft, the doubly-hinged pitinan, and theplunger, as set forth.

v3. The combination of the plunger having the upper inclined groove, g,with the roof of the frame having the correspondingly-inclined 3o cleatg', and devices, substantially as shown, for operating said plunger, asset forth.

4C. The. combination, with the pressurehead J and the geared rack J', ofthe pinion K and its shaft K', the pulley L, the friction-band L', 3 5having ratchets m m and the tension-screw Z, and the pivoted clutch M,as set forth.

5. The combination, with the ioor of the baleohamber, slotted at r, ofthe pivoted hook R, the laterally-moving block O, having a T- 4o headwedge-shaped at o, and the horizontallymoving operating-lever N, as setforth.

In testimony whereof I affix my signature in presence of two Witnesses.
